Explore a comprehensive 56-minute lecture on the evolution of carbonate deposition patterns in the Southeast Atlantic over the past 30 million years. Delve into XRF core scanning techniques used to approximate carbonate content at Wallis Ridge, and uncover insights into climate, cryosphere, and carbon cycle interactions since the early Oligocene. Examine the transition from a unipolar to bipolar world, the importance of carbonate deposition in the carbon cycle, and the previously understudied Atlantic Ocean carbonate deposition. Learn about the XRF core scanning process conducted at Site 1264 between 2011 and 2018, and how this data ensures stratigraphic continuity. Discover the three distinct phases of orbital imprint on CaCO3 deposition, including eccentricity-paced cyclicity during Miocene warmth and precession-driven deposition after the mid-Miocene climate transition. Investigate the onset of the Late Miocene Biogenic Bloom (LMBB), its global recognition, and potential origins. Gain new perspectives on nutrient distribution and its regional differences. Conclude with an overview of the CODD (Code for Ocean Drilling Data) tool and its application in analyzing 30 million years of CaCO3 data to understand climate, cryosphere, and carbon cycle interactions.
